Kaká insists Real Madrid do not view Saturday's La Liga clásico against Barcelona as an opportunity to rub salt into the wounds of the Catalans.

Madrid beat their rivals 3-1 at the Camp Nou on Tuesday to knock them out of the Copa del Rey, while Barcelona are also in danger of exiting the Champions League as they trail Milan 2-0 heading into the return leg of their last-16 tie in 10 days' time.

"We are not thinking about sending them into a crisis, we're just thinking about what we need to do," Kaká said. However, the Brazilian midfielder did concede Madrid had been lifted by Tuesday's result, adding that they now hope to close the gap on the runaway league leaders.

"It's always great for us to beat Barcelona," he said. "We have now shown we can beat anyone and that has made us feel very positive. We go into the game with a lot of confidence and we have to get three points tomorrow to reduce the gap from 16 points to 13."

With Madrid facing Manchester United in the second leg of their last-16 Champions League at Old Trafford next week, José Mourinho is expected to rest several of his usual first-team players against Barcelona. Kaká revealed the players had not been told who would play on Saturday at the Bernabéu but was excited about the prospect of facing Barcelona, as it would give him the chance to prove his worth in a big match.

"He hasn't told us what the team will be, he will make the decision tomorrow," Kaká said. "It could be a great occasion for me, to show that I can still do great things for the team in important matches. It will be a great opportunity for me if I play tomorrow."

The Spanish media has reported that Cristiano Ronaldo will be left on the substitutes' bench as a precaution ahead of the trip to Old Trafford, while the Catalan press believes that Eric Abidal, who has not played a competitive match for over a year following a liver transplant, could return to the Barcelona squad. However, Xavi has been ruled for Barça with a hamstring injury he suffered on Tuesday.
